摘要

A series of [2-(omega-phenylalkyl)phenoxy]alkylamines was synthesized and their receptor binding affinity was examined in vitro. These compounds showed an affinity for serotonin-2 (5-HT2) and dopamine-2 (D2) receptors. [2-(2-phenylethyl)phenoxy]alkylamine derivatives with a pyrrolidine or piperidine moiety in the structure showed higher affinity for 5-HT2 receptors but lower affinity for D2 receptors. Among these compounds, (S)-2-[2- [2-[2-(3-methoxyphenyl)ethyl]phenoxy]ethyl]-1-methylpyrrolidine, (S)-27, exhibited the most potent and selective affinity for 5-HT2 receptors. Furthermore, (S)-27 was effective in inhibiting 5-HT-induced vasoconstriction in vitro and platelet aggregation both in vitro and ex vivo.
